The objective of this PhD project is to develop efficient and sustainable chemical cleaning agents for membrane-based water treatment. The project will be executed in partnership with Panton McLeod Ltd (PM), a water quality engineering company based in Galashiels. The specific goals are:1) To develop acid-based formulations tailored for removal of foulant layers from polymeric membranes for water and wastewater treatment. We will investigate cleaning of foulants commonly found in water resources in Scotland and Northern England (e.g. fulvic and humic acid-rich natural organic matter, Mn, Fe) 2) To investigate the efficacy of chemical cleaning in membrane materials (e.g. polyamide, PVDF, cellulose acetate) spanning a wide range of membrane applications (e.g. ultrafiltration, nanofiltration, reverse osmosis).3) To characterize the effect of regular chemical cleaning on the long term membrane permeability/selectivity and material properties (e.g. permeability, rejection, molecular weight cut-off, hydrophilicity).Fit to EPSRC Strategic Priorities. Due to the current challenges presented in water management and provision, EPSRC has identified Water Engineering research area as a priority area, in which this project fits perfectly. Water is an economically important area to the UK, and EPSRC has a considerable body of funded research in this theme. The current portfolio for Water Engineering comprises 37 grants of total value £47M.

该博士项目的目标是开发用于膜水处理的高效且可持续的化学清洁剂。该项目将与位于加拉希尔斯的水质工程公司 Panton McLeod Ltd (PM) 合作执行。具体目标是：1) 开发专门用于去除水和废水处理聚合物膜上的污垢层的酸基配方。我们将研究苏格兰和英格兰北部水资源中常见污染物的清洁（例如富含黄腐酸和腐殖酸的天然有机物、锰、铁）2) 研究化学清洁在膜材料（例如聚酰胺、PVDF、醋酸纤维素）中的功效，涵盖广泛的膜应用（例如超滤、纳滤、反渗透） 渗透）。3) 表征定期化学清洗对长期膜渗透性/选择性和材料特性（例如渗透性、截留率、分子量截留、亲水性）的影响。符合 EPSRC 战略重点。由于当前水资源管理和供应方面面临的挑战，EPSRC 已将水工程研究领域确定为优先领域，该项目非常适合其中。水对于英国来说是一个重要的经济领域，EPSRC 在这一主题上开展了大量的资助研究。当前水工程项目组合包括 37 项拨款，总价值 4700 万英镑。
